I've used Doc over in Carrollton twice -first time was for my Rossi 720 revolver when the cylinder was out of spec, and the second time when he fixed the trigger pull on my grandfather's old 22 rifle. He did a good job on both. I have no idea how he would do on that job, or if he'd even undertake it, but you could stop by over there and see. I checked and he does have a website:

Don't expect much if you decide to call, other than an estimate on how long it would take if you left the gun. I think the waiting period is 6 months or so. I would recommend taking it there and showing them what you want done, so they can tell you if they can do it.
I make no guarantees, I just know what my experience is and that's it. Don't leave them your gun unless you're convinced they can do a good job.
Gunsmiths are very hard to find, by the way. There are tons of shadetree smiths, but the good smiths are typically buried in work and don't come out much.
